Patent EP-0479293-A1 (EP)
Inventor: KRAUSS PETER PROF DR
IPC: B03B9/06
Filed: 1991-10-02
Abstract: The invention relates to a method and a device for separating metal-containing waste components. The method consists in selectively removing light-weight iron material (2) with a magnet (16) arranged over the conveyor belt and removing heavier iron material (3) with a drum magnet (17). The remaining material (4) is separated into a lighter fraction (5) and a heavier fraction (6) by air separation (18). The lighter fraction (5), which comprises in particular plastic films, aluminium foils and paper, is comminuted (19) and fed to an aspirator (20). The aspirator (20) is equipped with two filters (21, 22) and an air separator (23) so that the separation of the input material into a plastic fraction (10), aluminium fraction (9) and into a fraction (11) which comprises heavy-metal particles is made possible. <IMAGE>

IPC: G10L15/20
Filed: 1991-07-11
Abstract: A digital signal processing system applies an adaptive filtering technique to sequences of energy estimates in each of two signal channels, one channel containing speech and environmental noise and the other channel containing primarily the same environmental noise. From the channel containing primarily environmental noise, a prediction is made of the energy of that noise in the channel containing both the speech and that noise, so that the noise can be extracted from the mixture of speech and noise. The result is that the speech will be more easily recognizable by either human listeners or speech recognition systems.

Abstract: Apparatus for enabling a telephone network (1) to establish connections between calling (2) and called telephones (40,41) in accordance with called telephone numbers identified with ones of a plurality of calling party credit cards (20). The apparatus is connected by data links (1050-1054) with data bases (50-54) maintained by each of the credit card companies (CO1-CO5) and each credit card company is identified by a credit card number received from a calling party. The received credit card number is transmitted over a data link to the data base maintained by a credit card company identified as having issued a credit card assigned the received credit card number for an on-line determination of the calling party credit card. The data links are monitored (10) and the telephone network is controlled to transmit an announcement (from 1111, 1101, 1121) to calling parties using credit cards issued by a credit card company maintaining a data base when there is a malfunction of a data link between the telephone network and the identified credit card company data base or if the credit card is identified as invalid.

Abstract: A method and apparatus for checking the correlation between all parts of a photofinishing order includes reading the identification numbers on at least some of the parts of the order using an optical character reader. The method includes processing the information received from the optical character reader to compensate for the inherent characteristics of optical character readers to misread portions of the numbers and includes a method of filtering misread and nonread information to prevent false alarm conditions in which an apparent mismatch is actually a misread, while minimizing the number of actual mismatches that are allowed through the system without causing an alarm. In one embodiment, a portion of the information is obtained in bar code form and a memory device is loaded with a table of bar code and optical character reader information for each order to maintain correlation between the order parts. The method includes the steps of assigning different error weights to various digits of the identification number and summing the error weights to determine when the sum exceeds a predetermined sum that will trigger an operator intervention alarm.

Title: Pharmaceutical aerosol formulation of solid polypeptide microparticles and method for the preparation thereof.
Inventor: PLATZ ROBERT M
IPC: A61K38/16
Filed: 1991-04-12
Abstract: Disclosed is a pharmaceutical aerosol formulation of biologically active polypeptide which is a human interferon or a human interleukin, which is characterized by the fact that said polypeptide is in the form of solid micronized particles having a predetermined median diameter. An aqueous solution of the polypeptide is lyophilized followed by milling into an appropriate particle size of 0.5 to 10  mu m in median diameter to target either an upper or lower respiratory tract. The polypeptide aerosol suspension prepared in a pressurized metered-dose inhaler and administered by oral inhalation was found to produce desired local and systemic effects in animal tests. The biological response obtained with the polypeptide aerosol compares favorably to the response obtained from parenteral administration.

Abstract: Le procédé décrit sert à amplifier les séquences d'acides nucléïques contenues dans une matrice et composées d'au moins un acide nucléïque ou d'un mélange d'acides nucléïques, dans lequel chaque acide nucléïque comprend au moins un brin. Ce procédé consiste à traiter la matrice avec au moins une amorce d'oligonucléotides possédant une séquence d'acides nucléïques sensiblement complémentaire de la séquence d'acide(s) nucléïque(s) de la matrice, dans des conditions telles que l'amorce soit amenée à se lier à un segment sensiblement complémentaire de l'amorce, de façon à produire des brins d'acide nucléïque sensibilisés par l'amorce. Les brins sensibilisés par l'amorce produisent des brins d'extension, lesquels contiennent l'amorce combinée à une séquence d'acides nucléïques sensiblement complémentaire de celle de la matrice dans une direction 5' à 3' à partir de l'amorce. Les brins d'extension sont ensuite traités avec l'amorce, ce qui produit des brins d'amplification qui sont à leur tour traités avec l'amorce. Les brins d'amplification sont traités de façon répétée avec l'amorce pour produire de grands nombres de brins d'amplification, ce qui rend les séquences d'acides nucléïques des brins d'amplification sensiblement similaires aux séquences d'acides nucléïques de la matrice d'origine.

Abstract: A device is provided in which a preparation tank 4 is connected to the inlet of a preparation pump 5 and, for a cement suspension circulation, is for its part connected by means of a circulation line 9 to the outlet of the preparation pump 5, and in which an injecting tank 24 is connected to the inlet of an injecting pump 27 and, for a cement suspension circulation, is for its part connected by means of a circulation line 33 to the outlet of the injecting pump 24. It is in this case desired for this device to be suitable in an improved way for a cement suspension of fine cement. This is achieved by a screen 12 being fitted in the circulation line 9 of the preparation pump 5 and by the preparation tank 4 and the injecting tank 24 in each case being surrounded by a cooling device 14 through which coolant flows and which is connected to a refrigerating unit 16 through which the coolant flows. The screen in the circulation line has the effect of preventing any formation of lumps and, since the cooling devices are provided, the preparation pump and the injecting pump can operate at higher speeds. <IMAGE>
